sudo chmod +x /home/xtreamcodes/iptv_xtream_codes/nginx/sbin/nginx;
sudo touch /home/xtreamcodes/iptv_xtream_codes/admin/.update;
sudo /home/xtreamcodes/iptv_xtream_codes/start_services.sh;

replace https://xtream-ui.com/install/balancer.py 
with https://bitbucket.org/emre1393/xtreamui_mirror/downloads/balancer.py

- HOW TO ADD DATABASE EDITOR BACK IN THE PANEL
Using File Zilla or something similar, add code from the DBCodeforsettings.php text file to line 910 
in settings.php in the admin folder and save.

Then upload the database.php to the admin folder.

If done correctly you will now see the DB editor back in the settings 
tab of the panel.  You will need to do this everytime you update the panel.  

- Auto db backup and send with mail or/and copy to rclone remote 
What it does, backups db as panel does, without logs, (optional)then compresses and sends it as your choice.
It works with xc crontab. Enable auto backup in panel settings.
Open it with a text editor(notepad++, vs code, etc), Read instructions, you only need to edit the 6 lines between 44-60.
